Nuki Opener - very old analogue doorbell


I am interested in getting the Nuki Opener. However, my door bell in my apartment seems very old and I can’t find a manufacturer.

Does anyone know if Nuki Opener is compatible with this system? Which cables do I connect to Nuki? Can I do anything wrong or damage anything?

Thanks a lot

Hi! Nobody can say for sure when it’s not in the compatibility list for the opener, you can just try then!
